Catch missing index in countReadsPerBin

[dpryan79]

Sita pointed this out via email:

In deepTools-2.5.0.1-install/lib/python2.7/site-packages/deeptools/countReadsPerBin.py

240 for x in self.bamFilesList:
241 try:
242 y = bamHandler.openBam(x)
243 except Exception as err:
244 print err # this is missing
245 y = pyBigWig.open(x)

openBam will throw an exception if bam is missing index. But in your code you catch that and try to read it as bigwig. And then it fails with a mysterious error about opening a bam file with pybigwig.

Can we check for that?

That's definitely a mistake on my part.

This is now fixed in the develop branch.
